IMPRovENlErn' IN PUMPS. l

To all whomit muy concern: I

.Be it known. that I, HENRY E. WoLooTr, of the town of Elbridge, in thecounty of Onondaga and State of New York, have invented a new and usefulSubmerged Force-Pump, forforcing and. raising water I 'shown in thedrawing, having pcrforatedheads, which may be either plain-or convex,brmingstrainers to ,prevent sediment or other foreign substances frompassing-into the cylinders and clogging them.

1 These valves are provided with cylinders, closed at the ends, andperforated to allow the water to pass into the cylinder' C C', when avacuum is produced.'

Valve-cylinders are lettered c c.

To cylinder O C' are attached two lother cylinders, D D',^inwhich'movevvertically the India-rubber pis-l .tous F F.

lhe cylinder C G is divided at E by the partition`4 shown in iig. 2,whiehseparates the cylinder into twovdistinct chambers.

The' cylinder() C is snrmountcd by the` chamber vH, in which iscontained two small cylinders, G G',

closed at the top and havin g each block-tin valves, which close bytheir own weight the holes c c. The valves Vare 'lettered B B'.

To the chamber H is attached :L 'metal tube, I, to convey the waterupward and thence out through 'the spout-K. f

The cylinders G G have their convex surfaces perforated to allow thefluid to pass into the chamber H.

lhe piston-cylndeis D D are left open at the top and flared at `theirmouths, to give facility in cleaning,.

obstructed. Y

The rods L L' are attachcd'to the pistonsl by means.

of screw-bolts formed at the ends of the rods, with plates or washers oneither sides of the pistons F Ff. I hese bolts serve to compress thepistons vertically, and expand them laterally when tightened, formingthereby a seltlpaeking. 4 Y

The arms M M, to which are attached the piston rods L L, are balanced atthe point O, and serve as levers to operate the pump.

The pump is operated as follows:

he cylinder G C' being submerged, and the arms M M being at rest, whilethe valves A A. and B B. are closed, I apply the power to the arms andlift the piston F.' A vacuum being produced inthe chamber C, the wateris allowed to pass through the perforated cap in the valve A; `thencethrough the perforated valve-cylinder c to the chamber C and thepiston-cylinder l The power being now reversed, the piston F is forceddownward, the valve A by the force of the water is thrown ont andclosed, as seen at A', fig. 2. The same force of water lifts thevalve Band is allowed to pass through the holes in the cylinder Gto the chamber.H, and thence through thetube I and out of the spout K. I i

lhe power being applied to the arm M gives the same result on the otherside of thepartition E, and thereby a double action is gained.

I do not claim. to have invented anything new iii the system of raisingand foreingwater or fluids.

f That I claim as my invention, and in which I def sire to be secured byLetters Patent, is

1. The valves A A,constructed as described, for the purpose set forth.

2. 'Ihe valves A A', pipes C C', tin-block valves B B', flaring-mouthcylinders D and D', and chambers G G', combined and arranged tooperatesubstautially as set forth.
